This is really easy to fix and hopefully Jiri can produce a patch since I
am about to leave for the weekend.
The git master has this in erc32 configure.ac. It should be in both sis/
configure.ac and erc32/configure.ac
in our gdb 8.2.1 with patches.
# Keep in sync with gdb's configure.ac list.
AC_SEARCH_LIBS(tgetent, [termcap tinfo curses ncurses],
[TERMCAP=$ac_cv_search_tgetent], [TERMCAP=""])
if test x$sim_cv_os_cygwin = xyes; then
TERMCAP="${TERMCAP} -luser32"
fi
AC_SUBST(TERMCAP)
The gdb version we are using has some old hack-ish code specific to Cygwin
and termcap which is
now not needed. Unfortunately, that same code is in sis/configure.ac.
Please and thank you. :)
